How to write CP_Boards.h for Raspberry Pi Pico?

[longware]

Arduino IDE says:
c:\Users\xxx\Documents\Arduino\libraries\Adafruit_CircuitPlayground-1.12.0/utility/CP_Boards.h:746:2: error: #error "Please edit CP_Boards.h with a hardware abstraction for this board"
746 | #error "Please edit CP_Boards.h with a hardware abstraction for this board"
| ^~~~~

I found that there are a lot of descriptions of the MCU in CP_Boards.h file,
but the number of #define constants/variables is different,
so I don't know how to write it。 -_-!
